DBConvert/ DBSync software are intended for performing migration tasks easily and reliably from MySQL/ MariaDB to Firebird/ Interbase. InterBase, Firebird, MySQL and MariaDB server connections may be set up as nodes for conversion/ synchronization in any combination. MySQL Dump files may be generated to bypass firewalls restriction, if you cannot use direct connection to servers.

DBSync software is dedicated to make synchronization from MySQL Server to Firebird and vice versa.
Insert, update and drop synchronization make overall synchronization possible and your database up-to-date.
